Thermal Phase‐Modulation of Thickness‐Dependent CVD‐Grown 2D In2Se3

open access: yesAdvanced Functional Materials, Volume 36, Issue 12, 9 February 2026.
A comprehensive study of CVD‐grown 2D In2Se3 reveals a distinct thickness‐dependent phase landscape and a reversible, thermally driven transformation between β″ and β* variants. In situ TEM electron diffraction and Raman spectroscopy reveal structural dynamics, while the structural invariance of the α‐phase in ultrathin regimes highlights its stability—

Circularly Polarized Polariton Lasing from Spin‐Momentum Locking in Deformed Plasmonic Kagome Cavities

open access: yesAdvanced Materials, Volume 38, Issue 9, 12 February 2026.
This paper describes room‐temperature polariton lasing with high circular polarization from deformed plasmonic Kagome lattice cavities strongly coupled to colloidal CdSe nanoplatelets. Spin‐selectivity from cavity modes resulted in control over the handedness of circular polarization as well as the direction of polariton lasing, opening prospects for ...

Improving Ionic Conformality Across Polymer Electrolyte|Electrode Interfaces

open access: yesAdvanced Materials, Volume 38, Issue 9, 12 February 2026.
Polymer electrolytes typically form physically intimate electrode interfaces but often fail to maintain continuous ionic pathways, critically limiting battery performance. Through strategic compositional design, this study introduces a molecular ionic composite electrolyte that effectively reduces interfacial ionic depletion, ensuring consistent ion ...
